Twitter / X Image Sizes 2026: The Complete Guide

Using the wrong image size on Twitter/X means blurry profile photos, stretched headers, or posts that get cropped in the feed. This guide covers every Twitter/X image size you need in 2026 — profile photos, headers, post images, and link cards.

Twitter/X Image Sizes at a Glance

Format	Size (px)	Aspect Ratio	Notes
Profile photo	400×400	1:1	Displayed as circle; max 2 MB
Header / cover photo	1500×500	3:1	Cropped on mobile; keep key content centred
Post image — landscape	1600×900	16:9	Best for wide shots and link previews
Post image — square	1080×1080	1:1	Safe default; displays fully in timeline
Post image — portrait	1080×1350	4:5	More vertical feed space
Link card image	1200×628	1.91:1	Pulled from og:image tag on your page
In-stream image	1600×900	16:9	Appears inside tweet timeline

Profile Photo: Keep It Centred

The recommended Twitter/X profile photo size is 400×400 px. It displays as a circle across the platform — in timelines, search results, and reply threads — so keep your subject centred with clear margin on all sides.

Maximum file size is 2 MB. For Verified Organizations with a gold checkmark, profile photos display as squares instead of circles, so edge-to-edge designs work for those accounts.

Header Photo: Design for the Crop

The header photo displays at 1500×500 px on desktop but gets cropped differently on mobile. The bottom portion is also partially obscured by your profile photo on the left. Design your key content in the central horizontal band and avoid placing text or logos near the edges or bottom-left corner.

Post Images: Landscape Gets the Most Space

X displays post images in the timeline at a 2:1 crop preview before a user clicks to expand. For the cleanest in-feed appearance:

Landscape (16:9) at 1600×900 px — the recommended size for single images; displays fully without cropping

Square (1:1) at 1080×1080 px — safe default; works well on both mobile and desktop

Portrait (4:5) at 1080×1350 px — takes up more vertical space in the feed; good for mobile-first content

You can attach up to 4 images in a single post. When multiple images are attached, X automatically arranges them in a grid layout.

Link Card Images: Controlled by Your Website

When you share a URL, X pulls the preview image from the page's og:image meta tag. The recommended size is 1200×628 px (1.91:1 ratio). If your page doesn't have an og:image tag, X may show no image or pull an unsuitable one. Use a tool like Yoast SEO or Rank Math to set og:image tags on every page you plan to share.

File Format and Compression Tips

X supports JPG, PNG, GIF, and WebP. To get the best result:

Use JPG for photographs — smallest file size with good quality

Use PNG for graphics, logos, or images with text — lossless compression preserves sharp edges

Max file size: 5 MB for static images, 15 MB on web

Max dimension: 8192×8192 px — images larger than this get auto-resized

Use sRGB colour profile — other colour spaces may shift after X's processing

Key Takeaways
